can you confirm that you have put a jumper on "5V AUX JUMPER SELECT PINS" between the 5V AUX and 5V INT pins on the duex.

if heater 3 is PWM1 then pwm 5 should be heater 7 not 5

M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds.

H5 becomes H7?

Nevermind the last question. I meant to ask that "duex.e5heat" becomes "duex.e7heat", in the M950 bellow?

M950 S0 C"duex.e5heat" ; create servo pin 0 for BLTouch

Veti

@campeancalin said in BLTouch M401 M402 test does not work:

M950 S0 C"duex.e5heat" ; create servo pin 0 for BLTouch

the configurator even suggest to do this
M950 S0 C"duex.pwm5" ; create servo pin 0 for BLTouch

campeancalin

There 2 options in the configurator : "duex.pwm5" and "duex.pwm5"(active low). Wht's the diferrence between them?

Veti

@campeancalin
the output value is inverted

@campeancalin your P0 should be P7 in your deploy and retractprobe.g

your P0 should be P7 in your deploy and retractprobe.g

P0 is correct for RRF3
P7 was RRF2

@Veti you are right sorry I pulled from my 2.05 version. and 3.1 I only have working on duet 3 so far.

campeancalin

Thank you again for the info @Veti. Everything works with "duex.pwm5" set up.
